Given numbers are 791,699,609,429
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 791,699,609,429 is 2292913623.
Find LCM of 791,699,609,429 with Prime Factorization
| 3 | 791, 699, 609, 429 |
| 7 | 791, 233, 203, 143 |
| 113, 233, 29, 143 |
Multiply the prime numbers at the bottom and the left side.
3 x 7 x 113 x 233 x 29 x 143 = 2292913623
Therefore, the lowest common multiple of 791,699,609,429 is 2292913623.
LCM formula is LCM(a1, a2, an) = (a1 x a2 x an)/{GCF(a1 x a2 x an) x common factors}
Firstly, we have to find the product of all the numbers.
791 x 699 x 609 x 429 = 144453558249
Then, let us find the GCF of these five numbers. To do so, we have to list down the factors for each number and choose the highest factor that is in all of the lists.
791 : 1, 7, 113, 791
699 : 1, 3, 233, 699
609 : 1, 3, 7, 21, 29, 87, 203, 609
429 : 1, 3, 11, 13, 33, 39, 143, 429
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 791,699,609,429, is 1.
Now, the common factors can be found like this.
791:7x 113
699:3x 233
609:3x 7x 29
429:3x 11x 13
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
3x 3x 7 = 63
Therefore, the value for common factors is 63.
Now that we have all the elements of the formula, we can plug them in to calculate the LCM.
LCM(a1, a2, an) = (a1 x a2 x an)/{GCF(a1 x a2 x an) x common factors}
LCM = 144453558249/(1x63)
LCM = 144453558249/63
LCM = 2292913623
Thus, we can understand that the LCM of 791,699,609,429 is 2292913623.
